SAW-FILING MACHINE.

SPECIFICATION forming part of Letters Patent No. 728,893, dated MayA 26,1903. Appleman flied rebmry 14.',1903. 'serial No. 143,344. (No modem TLZZ whom, it may concern:

Be it known that I, JOHN W. FOLEY, residing at Omaha, in thecountyvof'Douglas and State of Nebraska, have invented certain usefulImprovements in Saw-Filing Machines; and I do hereby declare that thefollowing is a full, clear, and exact description of the invention, suchas will enable others skilled in the art to which it appertains to makeand use the same, reference being had to the accompanying drawings,which form a part of this specification.

This invention relates to a new and useful improvement in saw-filingmachines.

The aim of my invention is to provide a simple machine adapted to besecured to a suitable tripod, to the upper end of which is secured apanel supporting a table, which table supports a suitable'guide-shaftupon which is suitably held a carrier, which carrier in turn receives avibrating file-holder, to which holder are adjustably secured aplurality of files. Y

In the accompanying drawings I have shown in Figure 1 an upper brokenfront view of a saw-filing machine embodying my invention. Fig. 2discloses a top view thereof with portions removed. Fig. 3 discloses auenlarged detail disclosing 'the forward holder members. Fig. 4 shows adetail disclosing the rear file-holding members, while Fig. 5 shows anenlarged sectional view disclosing the vibrating holder as used in myinvention. In carrying out the aim of my invention I use a rear foot 18,which by means of the hinges 17 is secured to a shelf C, and to thisshelf is secured a panel B, to the top of whic is secured a table B. 1Secured to the panel B and the shelf C ar the legs 19 19, secured bysuitable cross-bars 20, so that by means of the legs 19. and foot 18 atripod is provided which can be neatly folded up.

Secured to the shelf C by means of a holder K, provided lwith theratchet-faced coupling 72, which coupling may be locked by means of thescrew 7c, is an ordinary saw-vise A, this vise being used to secure thesaw-blade which is to be filed, this vise being provided below with theusual set-screw 1b', securing the holder K and the front jaw member 14,secured by the usual lever a, Working within Y sharpened.

the ears '14, as shown. This vise forms no part of my invention, beingan article sold upon the open market. The rear jaw A of this vise, asshown in Fig. 2, is held by means of the brackets e. Vertically andadjustably secured to the table B are the vertically-adj ustablethreaded holders 2l, locked by means of the nuts 22, and these holderssupporting the guide-shaft D, which shaft is shown in Fig. 1, and isapproximately in line with the upper end of the vise.

. Extending from the table B are two supporting-arms b, provided withthe notched lugs c, into which a saw may be inserted, these brackets bserving the'purpose of holding the saw or anumber of saws before thesame are sharpened and after they have been In using this machine anoperator, especially where meat-saws are being sharpened, oftenV has twoor three saws to be sharpened, and the saws notv being operated upon areheld upon the brackets b.

The guide-shaft D is slidably held within the holders 2l, so that thisshaft may be moved sidewise, sliding within the holders 2l. Secured tothis guide-shaft D by means of a screw 29, referring now to Fig. 5, is abottom plate 28, slotted at suitable points, as 'shown'at 26. Secured tothis bottom plate 28 are the roller-plates 12, suitably perforated toreceive the trunnions of the rollersf, two such lower plates '12'beingused, each plate supporting two sets of rollers. Secured above the lowerplates 12 are the top plates lO, also perforated to receive thetrunnions of the rollers f, and in order to hold these rollers suitablebolts are used, which pass through .collars 11 and through-the slots 26,so that these -bolts 25 un-ite the top and lower plates and collars andthese"instrumentalities in be noticed that these roller-plates 10 andv12 and the rollers f are used in sets upon the `opposite sides, and thebolts 25 are securedvv IOO and M, in front secured to the block 9,(disclosed in detail in Fig. 3,) these arms L and M being secured bysuitable pins and the screws t', as shown in Fig. 2.

The plate E, forming the vibrating holder, is provided with a slot, asshown in Fig. 2, adapted to receive the screw o', and a threaded openingadapted to receive the screw o, as shown in Fig. 4. The screw o isprovided below with a revolubly-held collar 23, provided with an openingm'.

Striding the forward block 9 are the adjustable straps 3 and 4. Thestrap 4 isheld upon the block by means of the tube 8', which extendsfrom the strap 4 and enters a slot U within the block 9. In Fig. 3 thetube 8' is disclosed, as is also the vertically-positioned slot 'v Thistube 8 formsa holder, which in front is adapted to receive the handle 8,as disclosed in Fig. 2. Positioned adjacent to the strap 4 is the strap3, this strap also being provided with a tubular holder 7; but thisholder 7 passes through a horizontal slot if, as shown in Fig. 3, andextending from the strap 3 is the loop 5, as shownin Figs. 2 and 3.These straps 3 and 4 are made to tightly clamp the block 9. In ordertosecure the strap 4, I provide the set-screw 9', (shown in Fig. 3,) whichscrews against the tube 8'. Extending through the strap 4 and into thetubeSisthele-holdingset-screw2. (Shown in Fig. 3.) Extending through thestrap 3, block 9, and entering the tube is-the filleholding set-screw1,. From this it Will be seen that the strap 4 is locked by means of theset-screw 9', while the strap 3, which cannot be vertically adjusted,may he laterally adjusted by means of the adjusting-screw 6. In order tosecure the files necessary to sharpen the teeth to the vibrating holder,I insert the point of one saw-file, as V, into the opening of theset-screw o', while the remaining end of the file is inserted into thetube 8' and secured by the screw 2. The second le 2 has its forward endinserted into the opening 0c of the collar 23,While the handle end ofthe file 2 is secured within the tube 7 by means of the set-screw 1. Asnitable handle Sis then secured to one of the holders 8' or 7. The lescan then be nicely adjusted by means of the screws 0', while the forwardend of the file maybe adjusted by means of the strap 4. The ile 2 isgiven proper adjustment by means ot' the screw o and the strap 3. Inorder that the screw o may be carried laterally from side to side, thesame is made to pass through a block 5, as shown in Fig. 4, the blocksliding within the slot j within the plate E, While the screw Works upand down in this block 5.

Now

screws o and o the iiles can be so adjusted vthat their cutting edgesmay be one-a little higher than the other, so that the second file willcut a little deeper than the rst le.

In the use of my saw-filing machine I secure the saw to be sharpenedwithin the vise and then place the files upon the teeth and vibrate theplate E until I have filed down a suitable distance. Then by means ofthe handle 8 I advance the plateE, which is slidably held by means ofthe instru mentalities upon the shaft D,one tooth and again operate theplate E,so that each tooth that is operated upon by the first file isthen engaged by the second file. From this it will be seen that I canmore quickly and expeditiously' file a saw, for the reason that if ittakes twelve strokes of a file to sharpen a tooth by means of my machineI need vibrate the files but six times, and so save half the laborrequired iu filing the saw under ordinary circumstances. The depth towhich the files are carried and the number of strokes required are ofcourse determined by the operator.

Now, having described my said invention, what I claim as new, and desireto secure by United States Letters Patent, is-

A saw-tiling machine comprising the combination of the followinginstrumentalities, to wit.: a tripod, a table supported by said tripod,a vise secured to said tripod, vertically -adjustable holders secured tosaid table, a guide-shaft slidably held within said holders, a bottomplate secured to said shaft, roller-holding plate adjustably secured tosaid bottom-plate, upon opposite sides, rollers within saidholding-plates, a plate forming a holder movably supported by saidrollers, arms extending from said holder-plate, a block provided with avertical and horizontal slot, secured to said arms, a screw providedwith a {ile-holding opening laterallyladjnstable within saidholder-plate, a screw provided with aloose collar secured to saidyholder-plate, said collar being provided with a file-holding opening, Vastrap clamping said block and vertically adjustable thereon, a

Vfile-holder securedV to said strap, a second in presence of twowitnesses.
